Comparison
AgentGate vs Snyk Agent Scan
Snyk Agent Scan (formerly Invariant Labs mcp-scan) is an inventory and scanner front-end for the commercial Snyk platform. AgentGate is a local-first security gate: scan, lock, and CI-gate the whole agent config surface with no account and nothing executed. Every row below was verified against thesnyk/agent-scanrepository — dates and sources indocs/COMPARISON.md.
| Capability | AgentGate | Snyk Agent Scan |
|---|---|---|
| Account / token required | None — fully local, works offline | Snyk account + SNYK_TOKEN for every scan |
| Executes your MCP servers during scan | Never — static analysis by default | Yes — stdio scans run the server commands (sandbox recommended by their docs) |
| Lockfile of the approved tool surface | agentgate.lock — names, descriptions, input schemas | None |
| CI drift gate | agentgate ci — non-zero exit + readable diff + SARIF | None in the OSS repo |
| Advisory database | Public, structured, 110+ entries, free JSON API | Proprietary Snyk platform |
| Agent skills (SKILL.md) scanning | Yes — plus commands, plugins, and lockfile drift | Yes |
| Client config discovery | Claude, Cursor, VS Code, Codex, OpenCode, Windsurf, and 20+ more | Broadest coverage (Claude, Cursor, Windsurf, Gemini CLI, VS Code, …) |
| CLI output stability | Stable JSON / SARIF / terminal table | Labeled "experimental and subject to change" |
Where AgentGate wins
- No account, no token, no data leaves your machine — scans work offline and in air-gapped CI.
- Static-only by default: scanning an untrusted config never executes it.
- The lockfile + drift gate catches rug-pulls — an approved server changing its tool descriptions upstream — which a point-in-time scanner cannot see.
- The advisory database is public and structured; Snyk's intelligence sits behind the platform login.
Where Snyk wins (honest)
- Broadest client auto-discovery in the ecosystem and a large commercial research team behind it.
- Platform features (dashboards, org policy, reporting) that a standalone CLI does not attempt.
- The largest community of the MCP scanners (2,800+ GitHub stars as of 2026-08).
